A point is an undefined term in geometry that expresses the notion of an object with position but with no size. Unlike a three-dimensional figure, such as a box (whose dimensions are length, width, and height), a point has no length, no width, and no height. It is said to have dimension 0. Geometric figures such as lines, circles, planes, and spheres, can all be considered as sets of points.
